raT-ENT OFFICE 2,185,665 FIREPLACE BOILER Charles Helmoth Ham,Darling-ton, S. C. I Application April 23, 1938, Serial No. 203,923 2Claims. (01. 126-132) Ehis'invention relates to'new and usefulimprovements in boilers, and more particularly to a water heatingboiler, and more particularly to a water, heating boiler. attachment forfireplaces.

The principal object of the present invention is to provide a waterheating attachment for fireplaces in the 'form of a hollow wall shellfor installation in a fireplace, to the end that water can be heated forvarious purposes such as room heating. v

Another important object of the invention is for the purposes stated.

Other objects and advantages of the invention willbecome apparent to thereader of the following specification. .In the drawings- Figure 1represents a front elevational view of the boiler. 1

Figure 2 is a side elevational view.

Figure3 is a vertical sectional view on a line 3-3 of Figure l.

, Figure 4 is a top planview section. g 6

Referring to the drawings, wherein like numerals designatelike parts, itcan be seen that the boiler consists of a back double wall structure andthe two side double wall structures 6, as well as the top wall section Iwhich is also of double wall construction and which extends acrossbetweenthe upper ends of the side wall structures 6, The inner edge ofthe top wall section'! is spaced from the upper end portion of the backwall 5. As before stated, each of these with a portion in walls is ofhollow construction for the receptionv of water which will be heated bya fire on the grateB. This grate 8 is supported by lugs 9 projectingoutwardly from the inner sides of the side wall structure 6. a

Pipes Ill and Ill-a extend from the side wall structures 6 and the topwall structure I respectively to various points of use.

It ispreferable that a fuse plug ll be provided in the bottom of theupper section 1 and also in the other wall structures if deemed con,-venient and practicable.

The spacezbetween the section I and the upper portion of the back ingl2.

wall 5 defines the flue'openf I As can be seen in Figure 3, the backwall structure 5 startsv to curve forwardly over the grate from thepoint a to the point D, the latter being adjacent the upper section 1..This re quires the flame and heat from the fire on the grate to contactthis back wall structure over an appreciable area of its inner surfaceas the products of combustion pass upwardly to the flue opening l2.

While the foregoing specification sets forth the invention in specificterms, it is to be'understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention, as claimed hereinafter.

Having described the invention, what is claimed as new is:

'1. In combination with a fireplace, a hollow double wall shellconstruction disposed into the fireplace and including spaced innerandouter sides/back and top walls providing a water chamber between thewalls, said top walls cooperating to form a flat horizontal tank at thefront of the fireplace connected at each side with said side walls, saidtank being. spaced from the back wall to form a flue opening meanscarand saidrear wall having its portion above" the grate and below thetank curvedforwardly to deflect heat forwardly against the under side ofsaid tank.

2'.I n combination with a fireplace, a hollow double wall shellconstruction disposed into the fireplace," said shell including a doubleback wall' structure, double side wall structures and a double top wallstructure, said wall structures being hollow and having directcommunication with each said walls terminating in a common horizontalplaneand said rear wall, below the tank being curved forwardly todeflect heat againstthe bot tom of the tank.
